Israeli Prime Minister Binyamin Netanyahu advised visiting Chairman of the US Joint Chiefs of Staff, Gen. Martin Dempsey Friday, Jan.20 that the time for action against Iran was now, for two reasons: First, the conviction that Iran has passed the point of no return for developing a nuclear weapon; and second, the diminishing prospects for a US-led embargo on Iranian oil to catch on before it is too late.

The Obama administration disputes the Israeli prime minister on both points, insisting there is still time for tough sanctions to incapacitate the Iranian economy and stop Tehran before it reaches the point of no return in its drive for a nuke. Israel insists that this pivotal point was reached four years ago in 2008.

Gen. Dempsey was exhaustively briefed on the Israeli position during his whirlwind interviews Friday with President Shimon Peres, Defense Minister Ehud Barak and three conversations with Chief of Staff Lt. Gen. Benny Gantz, one with key General Staff officers.

It was not by chance that Maj. Gen. (ret.) Asher Yadlin, until last year Israel chief of military intelligence, maintained in a detailed article in the Tel Aviv daily Maariv: “If Iranian leaders were to convene tonight and decide to go ahead with the secret production of a nuclear bomb, they already possess the resources and components for doing so. This [capability] was once defined as the point of no return. [As matters stand] now, Iran’s nuclear timeline no longer hinges on the calendar; it rests entirely on a decision in Tehran.”
